Part of problem is highlighted flaw (7)

Ross

I believe the answer is:

blemish

'flaw' is the definition.
(synonyms)

'part of problem is highlighted' is the wordplay.
'part of' indicates a hidden word.
'BLEMISH' is hidden in the letters of 'problem is highlighted'.

(Other definitions for blemish that I've seen before include "Stain - defect" , "deformity" , "Small flaw" , "acne?" , "Stain, flaw" .)

I've seen this clue in The Telegraph.
